im unable to google this one out: which filesystems are available, which contain any form of a data loss prevention in case the medium (hdd) itself will become faulty? and potentially automatically fix the corrupted file/bit/bytes
possible solutions i can think of (and the effect):
- internal raid to copy all data (partition size would be half the size of standard fs)
- sort of a XOR bit per each 2 bits (partition size would be 30% less than standard fs)
- some sort of control checksum/hash per each block of data.
- some sort of snapshots per each day
it happens a lot that my older files have some sort of I/O error due to the medium loosing particular bit(s). and at the same time i dont wont to setup all these RAID or RSYNC solutions.
